Following are the tests used for the identification of bacterial species based on the differences in the biochemical activities of different bacteria. Beta glucouronidase test is used for the identification of Escherichia coli. An enzyme is produced by E.coli which is beta D glucouronidase. Beta d glucouronidase in turn hydrolyzes beta d glucopyranosid uronic derivatives to aglycons and D glucuronic acid. Bile solubility test is used in laboratory for differentiation of alpha hemolytic Streptococci

Genetic Engineering • Description and How It Works Genetic Engineering is the process of manually adding new DNA to an organism. The goal is to add one or more new traits that are not already found in the organism, and to enhance or modify the organism’s characteristics. The process starts by identifying a gene that controls the desired trait and using various chemicals to extract it from the DNA strands. An insertion package is prepared that includes several unrelated genes that lets the trait gene

the genomic DNA, a band of genomic DNA (roughly 23kbp) is observed near the top of the gel. Further down the gel is another block of bands (ranging from 100bp ~ 2000bp) which is the degraded RNA. My group’s sample (lanes 16&17) shows similar band patterns to that of other groups where genomic DNA and RNA bands are seen but in differing quantities of DNA since some bands appear more faint than the others. In the gel electrophoresis of the plasmid DNA, 4 distinct bands of DNA are observed

1: Showing the beginning of the DNA replication process Diagram 2: Showing the leading and lagging strand and the direction they replicate. Also showing Okazaki Fragments, and the 3” to 5” end of DNA. The arrows in the above diagram show the 3” to 5” direction that the DNA replicates; starting in the origin of replication and moving towards the 5 direction, using Okazaki fragments in the Lagging strand. Diagram 3: Showing a more detailed version of DNA replication. Showing the enzymes

Gattaca is a movie directed by Andrew Niccol and the film is set in the "not too distant future." Andrew Niccol's perception of the future isn't what most people expect, but once thought about carefully it seems quite believable. This movie presents us with a new method in which society strives for perfection and it also makes us wonder if genetic engineering is morally correct. Your place in society in Gattaca is based on your genetic makeup and the way you were born. People born the way we know

Introduction Mids-1600s and an English scientist named Robert Hooke made observations. He observed strands of fungi among the specimens of cell his viewed. Robert Hooke in 1665 reported that living things were composed of title boxes or cells. He then devised the compound microscope and illumination system and stated that microbes were a life’s smallest structural units were cells. Then in 1670s, decades after, Dutch merchant named Anton van Leeuwenhoek made careful observations of microscopic organisms

Nanotechnology is introduced in 1980’s by which it is possible to build things at nano scale by controlling molecules at atomic level. In later years technology has accepted and improved and found its use in various fields including electronics, organic chemistry, biomaterials, medicine etc. Nanomedicine uses this nano scale particles for the benefit of mankind (Medina et al., 2007). Using these nano particles therapeutically has made a significant improvement in the field of medicine that is used
